Embodiment

Fig. 1 illustrates a part for the Motor Vehicle of the longitudinal regulator had according to one embodiment of the present invention in the mode of three-dimensional Local map.

Motor Vehicle have the form of two control cables 100 in gearshift traction gear, two at the traction backstop 201 of gear level in other words on selection lever 200 and two longitudinal regulators 1, described longitudinal regulator is illustrated in the mode of three-dimensional disassembly diagram in fig. 2.

Longitudinal regulator 1 has respectively with the matrix 2 of teeth portion 2.1 (with reference to Fig. 3) and the pull bar in tooth bar 3 form with pairing teeth portion 3.1.Pull bar 3 is connected with traction gear 100 enduringly, and matrix 2 releasably and is hingedly connected with traction backstop 201.

Longitudinal regulator 1 has lock 4 respectively, described lock can unlocked position shown in lock position as shown in Figure 5 and Fig. 3 spaced winding perpendicular to Fig. 3,5 the spin axis that extends of drawing rotate, on described lock position, lock makes pairing teeth portion 3.1 be formed with teeth portion 2.1 to be engaged, and lock makes pairing teeth portion 3.1 remove with teeth portion 2.1 to be engaged on described unlocked position.

Lock 4 has the cam 4.1 with circumferential surface, this circumferential surface changes along with the angle of rotation of the spin axis around lock 4 relative to the radial spacing of spin axis, and this circumferential surface (with reference to Fig. 5) in lock position makes pull bar 3 compress relative to matrix 2, and this makes pull bar 3 contact with the side (above Fig. 5) deviating from matrix and realize by this circumferential surface.

The draw direction (in figure 3 to the right) of cam 4.1 (with reference to Fig. 3) longitudinally regulator 1 on unlocked position is directed.

Lock 4 form fit ground in the dislocation shown in Fig. 4 is antitorquely fixed on matrix 2, described dislocation in the section of Fig. 3 perpendicular to drawing relative to unlocked position generation dislocation.Matrix 2 has chute for this reason, and cam 4.1 form fit ground in dislocation is antitorquely fixed in described chute, and chute is configured for the guide port of being guided to matrix 2 by lock 4 simultaneously.

Lock 4 can be parallel to spin axis and move to unlocked position from dislocation, and the drawing that is perpendicular to Fig. 3 moves.

In transformed loci (with reference to Fig. 4), lock 4 is overcome by pull bar 3 and is parallel to moving of spin axis and is fixed.Pull bar 3 has stop surface 3.2 for this reason, described stop surface limits the movement (with reference to Fig. 3) of lock 4 in the draw rod positions of an axis, and can realize the movement (with reference to Fig. 5) of lock 4 in the draw rod positions along another axis that draw direction offsets with it.

Lock 4 by the lock spring part of spring 5 form in the form of a ring on lock position by pretension.Ring-spring utilizes that end 5.1 is antitorque to be bearing in the gap of lock 4 regularly, utilizes another end 5.2 to be bearing in and is positioned on the flange of outside matrix 2.

Lock 4 has rod member 4.2, for manually making lock to unlocked position rotation and moving.Limit to rod member 4.2 form fit of wedge shape the swing offset of lock 4 to lock position and unlocked position, method is, this rod member backstop is on the flange 2.2 of the wedge shape of matrix 2.In addition, rod member 4.2 also limits to form fit the moving displacement to unlocked position, and method is, the surperficial backstop towards matrix 2 of rod member at matrix 2 towards on the surface of rod member.

Pull bar 3 can be bearing on matrix 2 to form fit vertically or along draw direction movably.In addition, be rotatably supported on matrix 2 to pull bar 3 form fit.Pull bar 3 has two mutually opposing protuberances 3.3 for this reason, and described protuberance movably and be rotatably supported in the corresponding groove 2.3 on matrix 2.

Matrix 2 has backstop 2.5, so that make pull bar 3 overcome the rotation of the occlusal position shown in Fig. 5 and form fit be fixed in the bearing position shown in Fig. 3, teeth portion 3.1 of matching in described bearing position is removed with teeth portion 2.1 and is engaged, and teeth portion 3.1 of matching in described occlusal position is formed with teeth portion 2.1 and is engaged.By pull bar 3 moving axially (in figure 3 to the right) along draw direction from its bearing position, pull bar 3 can in this wise with backstop 2.5 separately, thus pull bar 3 can be rotated on occlusal position.

Pull bar 3 reverse draw direction in longitudinal regulator 1 in bearing position (with reference to Fig. 3) is releasably locked.Matrix 2 and pull bar 3 have opposed lug 2.4,3.4 for this reason, and described lug is form fit ground locking mutually (with reference to Fig. 6 A) in bearing position.

That the locking of pull bar 3 in bearing position is got loose by the link that can engage with matrix 2, be released by this link and the locking of matrix 2 in other words, the form of described link universal joint 7 spherical in shape is for being connected with the traction backstop 201 of Motor Vehicle.Universal ball joint 7 has protuberance 7.1 for this reason, and when universal ball joint 7 engages with matrix 2 (as shown in the order illustrated according to Fig. 6 A → Fig. 6 B), described protuberance makes the support generation resiliently deformable of lug 3.4.

Pull bar 3 by the pull-rod spring part in stiff spring 6 form vertically at bearing position (in figure 3 left) pretension.In addition, pull bar 3 passes through same stiff spring 6 in a rotative pattern towards bearing position pretension (in figure 3 in the counterclockwise direction in other words mathematically positively).Two inflexion points of stiff spring 6 on matrix 2 and pull bar 3 or point of action are disposed such, thus the torque towards bearing position is applied to (in figure 3 in the counterclockwise direction in other words mathematically positively) on pull bar 3 by the tractive force that the stiff spring 6 by compressing is applied.

In order to assemble longitudinal regulator 1, longitudinal regulator is provided to correspond to the state shown in Fig. 3, lock 4 is antitorque in dislocation is in this state fixed on matrix 2, its mode is, the cam 4.1 of lock is antitorque to be fixed in the shaping through hole of the correspondence of matrix 2, and wherein, pull bar 3 is pulled spring 6 to bearing position traction (in figure 3 left and in the counterclockwise direction), and is fixed with overcoming rotation towards occlusal position (in figure 3 along clockwise direction) and form fit by backstop 2.5 at this place.

In this case, universal ball joint 7 acts in traction backstop 201, situation as shown in Figure 5.Thus, the lug 3.4 of pull bar 3 is got loose by the protuberance 7.1 of colliding of universal ball joint 7 with the locking of the lug 2.4 of the relative of matrix 4 (order illustrated with reference to Fig. 6 A → Fig. 6 B), and being drawn out along draw direction () from its bearing position with back stay 3, and now stiff spring 6 tensioning in Fig. 3,5 to the right.

Stiff spring makes pull bar 3 correspondingly towards bearing position tensioning, thus make the pairing teeth portion 3.1 of pull bar keep further removing with the teeth portion 2.1 of matrix 2 being engaged, but due to pull bar 3 moving axially away from backstop 2.5, backstop 2.5 no longer hinders form fit ground towards the rotation of occlusal position.Being moved axially by pull bar 3 also makes stop surface 3.2 move, thus makes stop surface no longer form fit limit the movement being parallel to its spin axis of lock 4.

From above, (with reference to Fig. 1) spin axis of being parallel to lock moves the rod member 4.2 of lock 4 to present workman, thus makes lock be converted into its unlocked position (dislocation and unlocked position Fig. 3 sectional view perpendicular to spin axis) from its dislocation.Thus, the through hole of cam 4.1 and matrix 2 or chute are removed and are engaged, and can rotate around the spin axis of matrix.This automatism is in torsional spring 5, and described torsional spring makes cam 4.1 rotate relative to pull bar 3, and makes the pairing teeth portion 3.1 of pull bar compress to be engaged with the teeth portion 2.1 of matrix 2 like this.Fix the length of longitudinal regulator 1 in this way.

In order to dismantle, especially in order to change length, workman can counterrotating rod member 4.2 simply, so that cam 4.1 makes pairing teeth portion 3.1 no longer mutually be engaged with compressing with the teeth portion 2.1 of matrix 2.Stiff spring 6 makes pull bar 3 produce from its occlusal position subsequently, and pull bar can relative to matrix 2 along draw direction or reversely to move in draw direction.If workman makes again to be unclamped by the rod member 4.2 of torsional spring 5 pretension, then stiff spring makes cam 4.1 steering linkages 3 again, be engaged so that pull bar makes pairing teeth portion 3.1 compress with the teeth portion 2.1 of matrix 2 again, and (newly) length of fixing so longitudinal regulator 1.

Although foregoing description has set forth exemplary mode of execution, but be noted that also there is a large amount of modes of texturing.In addition should be noted that described exemplary embodiment only as from, and should not limit protection domain, application and structure by any way.But those skilled in the art obtain the instruction at least one illustrative embodiments being carried out transforming by foregoing description; wherein; especially multiple change can also be carried out in its function and layout, only otherwise the protection domain departed from given by claim and its equivalent technical characteristics combine to described parts.
